LoVoCCS. III. Third Generation Pipeline & The Hercules Supercluster
Anthony M. Englert, Shenming Fu, Ian Dell'Antonio +29
The Local Volume Complete Cluster Survey (LoVoCCS) is a volume-complete survey of over one-hundred nearby (), X-ray luminous ($L_{500} > 10^{44} \text{ erg s}^{-1}…
Weak Lensing Spectrotomography: A1767 and A2065
Jubee Sohn, Ian P. Dell'Antonio, Margaret J. Geller
We describe spectroscopic tomographic weak lensing measurements (spectrotomography) for two rich clusters of galaxies, A1767 and A2065, based on extensive spectroscopy and Subaru/H…
Identification of Compact Groups of Galaxies in IllustrisTNG300
Seungwu Yoo, Jubee Sohn
We identify compact groups of galaxies (CGs) in the IllustrisTNG-300 simulation using a Friends-of-Friends (FoF) algorithm. Our approach is designed to be comparable to systematic…
The Stellar Mass Function for Nine Massive Galaxy Clusters in the Local Universe
Jong-In Park, Jubee Sohn, Margaret J. Geller +2
We measure galaxy stellar mass functions (SMFs) for nine of the most massive galaxy clusters in the local universe () using deep and complete spectroscopy from the…
Velocity dispersion functions of pressure-supported galaxies in EAGLE simulations with varying active galactic nucleus feedback
Jungwon Choi, Jubee Sohn
We investigate the stellar velocity dispersion functions (VDFs) of pressure-supported galaxies in the EAGLE cosmological simulations. The central stellar velocity dispersion is one…
The Redshifts from 122 Bands: Comparative Redshift Forecast for Low-Resolution Spectra from SPHEREx and 7-Dimensional Sky Survey (7DS)
Jangho Bae, Bomee Lee, Myungshin Im +21
The recently initiated SPHEREx and 7DS surveys will deliver low-resolution spectra () for hundreds of millions of galaxies over the optical to near-infrared range…
